Hi Michael My installation was onto a 300gig unformatted partition. I did one change from the defaults, and only one change. I changed /home from xfs to ext4. That means that leap for the default installation appears twice in the list. It may be that it happens because I have multiple partitions with two other distributions. When I install a distribution, I do the sha256sum confirmation of the iso after I burn a flashdrive, I always run a "test and install" step to verify the flashdrive. The leap flashdrive fails the test. The flash drive was created using dd. The fact that leap appears more than once can be considered a feature, as opposed to a problem. If it becomes a feature, then we can close this bug and open one for the "Check Installation Media" error.
